This remarkable form has the appearance of a Dasy- 

 lahris, but the emarginate eyes and tridentate mandibles 

 do not allow of its being entered under that genus. The 

 shape of the head and the multicarinated median segment 

 serve to distinguish it from all African forms of Mutilla 

 known to me.

2 . Black, basal two-thirds of the mandibles, antennal tubercles, 

 apex of scape, basal two joints of the tiagellum of the antennae and 

 the thorax dorsally and on the sides red. Head, thorax and abdomen 

 covered with sparsely scattered erect yellowish hairs, the basal 

 abdominal segment with an apical triangular patch in the middle 

 above the 2nd, 3rd and 6th segments with dorsal, and the 2nd to 

 the 6th segment with ventral bands or fringes of similar pubescence. 

 Head subquadrate broader than long and a little broader than the 

 thorax, very closely and somewhat coarsely punctured ; mandibles 

 somewhat obtuse at apex, antennal tubercles rounded, prominent; 

 eyes placed rather forward equidistant from the occiput and the base 

 of the mandibles, head well developed behind the eyes. Thorax 

 rectangular not broader or narrower posteriorly than anteriorly 

 above coarsely punctured the sides crenulate, the pronotum slightly 

 arched in front ; the median segment abruptly truncate, the posterior 

 angles above well marked the margin with a row of five pos- 

 teriorly-pointed long spines in the middle and two much shorter 

 ones on each side at the angles. Abdomen more finely punctured 

 than the thorax, basal segment short, with its ventral carina deep 

 and incised in the middle, 1st to the 6th segment smooth along 

 their bases, sparsely punctured along their posterior margins, the 

 pygidial area well defined very firmly punctured. 

 Length $ 9 mm.
